Description
Technical field
This utility model relates to a kind of device adopting water (liquid) type of cooling protection cable in fire fighting device and conveying electricity facility.
Background technology
Domestic Super High project commonly use for rigidity mineral insulated cable (BTTZ) and flexible mineral insulation fire-resisting cable, although have many good qualities such as the damage of current-carrying capacity voltage big, shock-resistant, mechanical resistant, nontoxic, explosion-proof, the waterproof of Halogen etc.；But there is deadly defect: when fire temperature reaches more than 950 DEG C, can only load carrying 60 minutes, it is impossible to meet the needs that Super High fire-fighting is powered 180 minutes, therefore there is limitation and safety is not high.
Utility model content
In order to solve the deficiencies in the prior art part, the purpose of this utility model is in that to provide a kind of cable protecting device being provided with cable protection pipe and coolant, both can seal power transmission cable, it is also possible to power transmission cable is cooled down.
For achieving the above object; the technical solution adopted in the utility model is: a kind of cable fire protection device; including one or above protected location; each protected location includes shell; it is located at the cable protection pipe in shell at least one, outside the two ends of described cable protection pipe are positioned at shell after passing from the two ends of shell respectively；Described shell is imported and exported at least provided with a coolant, is perfused with coolant in the enclosure.
Further; also include at least two bracing frames for being fixed on outer casing inner wall by a cable protection pipe; wherein bracing frame upper end is connected with cable protection pipe and lower end is connected with shell inner bottom surface, and another root bracing frame upper end is connected with inwall on shell and lower end is connected with cable protection pipe.
Described cable protection pipe is three, every cable protection pipe is equipped with two bracing frames and is connected with outer casing inner wall；Dowel is adopted to connect between adjacent two cable protection pipes.
It is four that described coolant is imported and exported.
Described shell is made of one piece, and the cross section of shell is square；The inner and outer wall of shell is equipped with high-temperature flame-proof coating.
nullAdvantageous Effects of the present utility model: protection device can be made up of one or more protected locations，Each protected location forms by shell and interior complex root cable protection pipe thereof，The end of cable protection pipe is positioned at the outside at shell two ends，And on shell, it is provided with coolant (cooling air) inlet，Inlet can also as outfall，Consequently facilitating coolant is injected in shell，Cable protection pipe is made to be soaked in coolant，Cable passes from cable protection pipe，Thus，Well solve fire-resisting cable internal copper conductor heat dissipation problem，Fire resistance period was more than 3 hours，Copper conductor surface temperature is down to less than 100 DEG C，Compared with the existing technology，This utility model cost is extremely low，Reliability is high，There is very high popularizing value and commercial value，Good Social benefit and economic benefit can be brought to relevant industries.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is schematic cross-section of the present utility model.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that this New Scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1-2; a kind of cable fire protection device, including one or above protected location, each protected location includes shell 1; at least one cable protection pipe being located in shell 2, outside the two ends 201,202 of described cable protection pipe are positioned at shell after passing from the two ends of shell 1 respectively；Described shell imports and exports 101 at least provided with a coolant, is perfused with coolant 3 in the enclosure.
And the end of the shell 1 of each protected location is provided with and is tightly connected accessory, consequently facilitating as required multiple protection device units are linked together.
Also include at least two bracing frames 4 for being fixed on outer casing inner wall by a cable protection pipe; wherein bracing frame upper end is connected with cable protection pipe and lower end is connected with shell inner bottom surface, and another root bracing frame upper end is connected with inwall on shell and lower end is connected with cable protection pipe.
In the present embodiment, described cable protection pipe 2 is three, every cable protection pipe is equipped with two bracing frames 4 and is connected with outer casing inner wall；Dowel 5 is adopted to connect between adjacent two cable protection pipes.The quantity of cable protection pipe 2 is determined according to practical situation.
It is four that described coolant imports and exports 101, and coolant is imported and exported 101 quantity and determined according to practical situation, and it can as cooling liquid inlet, outfall, it is possible to as cooling air import.
Described shell 1 is made of one piece, and the cross section of shell is square；The inner and outer wall of shell is equipped with high-temperature flame-proof coating.
Compared to existing technology, this utility model has the advantage that
(1) thoroughly solving existing fire-resisting cable in the market, fire-resistant weak effect, in cable, copper leads not that radiating effect is poor, and the problem of temperature rise improves the service life of cable, it is ensured that the fire-fighting continued power time reaches more than 3 hours.
(2) owing to the use of refractory material is greatly reduced, it is not necessary to amplify copper conductor cross section, whole scheme makes product integrated cost reduce by more than 50%.
(3) owing to water (liquid) temperature is the highest 100 DEG C, when being water-cooled, conductor maximum temperature-rise value is lower than 70K, and conductor pressure drop is low, does not affect the oepration at full load of circuit.
(4) owing to solving cable fire protection device internal heat dissipating problem very well, make the protector the longest fire resistance period of inner cable more than 180 minutes.
(5) product interchangeability is very good, owing to degree of protection reaches IP65, can be used for by bad environments places such as fire resistance period requirement 60 minutes, the places such as 90 minutes, 120 minutes, 180 minutes and moist or high temperature.
Although depicting the invention by embodiment, skilled addressee will appreciate that, this utility model has many deformation and is varied without departing from spirit of the present utility model, it is desirable to appended claim includes these deformation and is varied without departing from spirit of the present utility model.
